Attenuated total reflection infrared (ATR-IR) spectroscopy

Attenuated total reflection (ATR) is a sampling technique used in conjunction with infrared spectroscopy which enables samples to be examined directly in the solid or liquid state without further preparation. ATR uses a property of total internal reflection resulting in an evanescent wave. A beam of infrared light is passed through the ATR crystal in such a way that it refl… WebATR-FTIR spectroscopy (Varian 670-IR with PIKE Gladi ATR accessory) is performed at room temperature in the range between 450–4000 cm–1 to detect any interaction between the drug and the polymer matrix. The usual estimated interaction between these components is the formation of hydrogen bonds between the amino groups of the drugs … graph refill pad https://mdbrich.com
